Dendera – Egypt / Photo from Nikki&Michi
However, in the Temple of Dendra in Egypt a stone relief seems to feature an electric lamp throwing light. The believers also pointed out that there was no soot in any of the pyramid shafts or underground tombs of Egypt, which must have stayed if the workers used fire as a source to make the elaborate carvings and decorations within the chambers. Many think, there must have been an alternate source of light other than fire and this speaks volumes in support of the battery theory. The concept of using polished copper plates for mirrors does not hold much ground as a promising source of light.
